NECESSITY,
FUNCTION, AND CONFORMITY: KRS 224.10-100 requires the Environmental and Public
Protection Cabinet to prescribe administrative regulations for the prevention,
abatement, and control of air pollution. This administrative regulation provides
the list of hazardous air pollutants pursuant to 42 U.S.C. 7412(b) as amended
in the Federal Register, 61 FR 30823, June 18, 1996 and the list of source
categories and subcategories, as published in the Federal Register, 57 FR
31591, July 16, 1992.

Section 1.
Definitions. As used in this administrative regulation, terms not defined in
this section shall have the meaning given to them in 401 KAR 63:001.

(1)
"Act" means the Clean Air Act promulgated at 42 U.S.C. 7401-7671q, as
amended by Pub.L. 101-549, November 15, 1990.

(2) "Area
source" means a stationary source of hazardous air pollutants that is not
a major source.

(3)
"Hazardous air pollutant" means a substance listed in Section 2 of
this administrative regulation.

(4) "Major
source" means any stationary source or group of stationary sources located
within a contiguous area and under common control that emits or has the
potential to emit considering controls, in the aggregate, ten (10) tons per
year or more of a hazardous air pollutant or twenty-five (25) tons per year or
more of any combination of hazardous air pollutants, or a lesser quantity which
the cabinet may establish on the basis of the potency, persistence, potential
for bioaccumulation, or other characteristics or relevant factors pertaining to
the pollutant.

(5)
"Stationary source" means a building, structure, facility, or
installation which emits or may emit an air pollutant.
